This unit will cover the concepts dealing with cell growth and division. Upon conclusion students will understand reasons for cell growth and division, the processes of cell division, and limitations to division. To start the unit I will begin covering cell growth, first we will cover limitations to cell sizes and why cells need to grow. Going from that we will cover the processes of cell division and reproduction ,learning asexual and sexual reproduction. Students will do a lab on cell surface area using different sized boxed cubes comparing surface area to volume. The next part of the unit will go into depth of the process of cell division including the cell cycle, mitosis and cytokinesis. Students will create a cell cycle flip book that will help reinforce the cell cycle and mitosis. From there we will then move on to cell cycle regulation covering the cell cycle controls and uncontrolled cell growth. Lastly the unit will then go into cell differentiation covering cells special function, stem cells and stem cell research. The students will be assessed with a unit exam.
This unit on cell growth and division will be important in gaining a base knowledge to help continuing on to the next unit on genetics and furthermore DNA and protein synthesis.
I will assess my students in a variety of ways throughout the unit. During lessons I will ask questions to gain knowledge on previous topics learned. There will be homework assignments given to help reinforce important topics covered. A formative assessment in the form of small activites such as the surface area lab, the cell cycle flip book and the stem cell research activity will give students more practice and knowledge. A summative assessment in the form of a cumulative unit exam will be given at the conclusion of the unit.
Rationale
I made this topic meaningful for students by using a variety of outside resources, real life examples in the form of hands on labs, articles, and activities to help drive home the importance of the top of cell growth and division. I used presentations to help teach topics. With the powerpoint presentations students took interactive notes so they could listen to the information that was being taught as well as retain and remember the important facts by filling in missing information. I made use of inquiry by starting each lesson with a series of questions for open discussion. These questions were to understand the prior knowledge students have before the lessons or review of previous lessons. With the opening and closing questions within each lesson I can assess what information is learned by students, what information do students need a little more help with. These questions were to help students to think about the lesson at hand for that day. I will sequence the lessons to show how they build off of eachother to the main learning outcome of mutations and cancer. Students will do a lot of hands on work with creative activites, reading and answering questions to help make sense of the materials that are provided. The work that is completed by the students will be assessed to see the knowledge that is learned by students.
